Energy saving steam trap concept is a Gem


Elantas Deatech, a member of the global specialty chemical group Altana AG, and a producer of insulating materials for the electrical and electronics industry, is achieving significant savings in steam consumption at its site in Ascoli Piceno, Italy, following the installation of Thermal Energy International’s Gem steam traps

lantas Deatech has now replaced all of the mechanical steam traps on its process, utilities and steam distribution pipeline with the Gem venturi orifice design.


Prior to the installation of the Gem steam traps, the mechanical traps regu- larly failed open, closed or partly open, necessitating regular replacement and maintenance. It was calculated that due to trap failure Elantas Deatech was wasting a large proportion of its steam production, which in turn was increas- ing energy costs.


In 2008, following a presentation at the Ascoli Piceno site, Thermal Energy International organised a bucket test to measure the live steam loss through the trap at various condensate load conditions. This is said to have proved that Gem technology was significantly more efficient over varying loads. Instead of utilising a valve mecha-


nism to close off steam for maximum energy and water conservation, the Gem steam traps use their venturi orifice design to effectively drain condensate from the steam system. As the Gem steam traps have no moving parts to wedge open or fail, it provides reliability necessitating only minimal maintenance and requiring no spares, testing or monitoring equipment. Thermal Energy International’s local engineer began converting the whole site including drip legs, heating systems and tracing applications. Support was provided by Elantas Deatech’s technical department in sizing the traps for some specific chemical processes.


“Thermal Energy International has supported the project throughout with a survey of the steam traps, a payback report and bucket test,” says Mr Giorgio Monni, plant manager at

Elantas Deatech’s Ascoli Piceno plant. “The Gem venturi steam system has provided us with real savings and the prospect of a large reduction in main- tenance costs.”

Such has been the success of the Gem technology at the Ascoli Piceno site that Thermal Energy International received an additional order for Gem steam traps for the company’s site in China and this year received a further order for the Ascoli Piceno plant. Available in a wide range of sizes for a full cross section of applications, the Gem steam traps are manufactured from corrosion resistant stainless steel and are guaranteed for 10 years, eliminating the need for repair or replacement. The Gem steam traps can provide a fast payback from reduced energy costs and increased equipment reliability. In addition it can improve product processing by enhancing process control, and can also reduce equipment repairs, downtime and replacement costs.


powertherm range of Combined Heat & Power (CHP) systems. By combining its expertise with that of its European partners, SEVA AG and Tedom, shentongroup now supplies its powertherm range in over 60 sizes ranging from 7kW to 2MW and in five package styles that include open sets, acoustic enclosures, compact series, containerised and total pre-fabricated plant room packages. In addition, powertherm is available with seven different fuel types including natural gas, LPG, biogas, vegetable oils, biodiesel, PPO and mineral diesel.


The package design can encompass all the CHP components within an acoustic enclosure thereby providing very low noise output plant room environments together with neatness of design and ease of access. Powertherm is also said to eliminate the possibility of brown or black outs as well as improve the quality of power delivered to businesses. The system’s synchronising controllers

enable powertherm to run in sync with a standby generator or the normal mains supply. Powertherm’s waste heat recovery provides heating for hot water, space heating or even air conditioning. This reduces energy consumption and enables commercial and industrial customers to offset gas and electricity consumption. The system’s low exhaust emissions ensure that powertherm can meet total compliance with existing and pending UK regulations. The powertherm series is available with a maintenance package that includes shentongroup’s Internet based remote monitoring system, which provides an automatic indication of any faults or changes to operational efficiency. Customers benefit from Infinium24 or ThermoCare, guaranteed fixed cost maintenance plans that ensure all components are maintained. This ensures the efficiency of the CHP system is at peak level throughout its life and is a mandatory requirement for most forms of government funding, and Carbon Trust initiatives.


Infinium 24 allows a true ‘whole of life cost’ to be calculated accurately therefore allowing the return of investment to be accurately predicted and also enables energy cost savings to be guaranteed. Offering several innovations from shentongroup and its manufacturing partners, SEVA AG and Tedom, the powertherm series is said to enhance the energy profile of a site whilst improving its energy costs and reducing its carbon footprint. shentongroup
